If selected, the menu item typically appears with a checkmark next to it. If unselected or deselected, the menu item appears without a checkmark. Like a regular menu item, a check box menu item can have either text or a graphic icon associated with it, or both. <p> Either <code>isSelected</code>/<code>setSelected</code> or <code>getState</code>/<code>setState</code> can be used to determine/specify the menu item's selection state. The preferred methods are <code>isSelected</code> and <code>setSelected</code>, which work for all menus and buttons. The <code>getState</code> and <code>setState</code> methods exist for compatibility with other component sets. <p> For further information and examples of using check box menu items, see <ahref="http://java.sun.com/docs/books/tutorial/uiswing/components/menu.html">How to Use Menus</a>, a section in <em>The Java Tutorial.</em> For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the <a href="doc-files/Key-Index.html#JCheckBoxMenuItem">JCheckBoxMenuItem</a> key assignments. <p>⌨️ 快捷键说明
